Black and white cards are ideal for 0-6 month babies because strong contrast is easiest to see. With calm sessions and gentle movement, you can support early visual skills.
Why use contrast cards?
Supports visual development
Bold contrast helps immature visual systems focus.
Builds attention
Simple patterns encourage short periods of steady looking.
Encourages tracking
Slow movement helps eyes learn to follow.
